Abstract
A rotational speed detector which is incorporated in an antiskid brake system for an automobile to detect a rotational speed of a wheel. A rotational speed sensor assembly which is provided on either one of the outer and inner rings of a wheel is biased toward a sensor rotor that is provided on the other of the two rings in such a manner that the sensor assembly is slidable on the sensor rotor, thereby maintaining the distance between the rotational speed sensor assembly and the sensor rotor at a constant level.
